This invention relates to improvements in washing machines and has particular reference to a washing machine for handling large quantities of clothes and discharging them in a relatively dry condition. y

The principal object of this invention is to provide a washing machine wherein several loads Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which'like numerals are. employed to designate like parts throughout the same,

Fig. I is a vertical cross sectional view of my device;

Fig. 11 is a cross sectional view taken on the line II--II of Fig. I;

Fig. 111 is a fragmentary detailed view taken on the line IIIIII of Fig. I and on an enlarged scale;

Fig. IV is a cross'sectional view taken on the line IVIV of Fig. I; and Fig. V is a fragmentary detailed view'of one of the eccentrics.

In the washing of clothes, particularly in laundries; it is important to handle the clothes as expeditiously as possible. This can be best done by employing quick .washing methods and by ments in counterdistinction to employing laundry mesh bags 'in which separate clothes are placed, and, also, the laundry mesh bags do not permit the proper washing of the clothes. As

- a result, strong bleaches must be employed,

which bleaches are harmful to the clothes.

I have, therefore, provideda machine which will overcome some of the difliculties now encountered in laundries;

In the accompanying drawings wherein for the purpose of illustration is shown a preferred,

embodiment of my invention, the numeral 5 designates the base plate upon which standards 6 are positioned. These standards support a plate 1 upon'which the casing 8 is mounted. This casing has a bottom 9 and an upstanding collar ll.

, maintaining the clothes in separate compartof which are valves 63',(see Fig. III).

valves permit water to flowthrough. a port 64 Within the casing is positioned a tub l0 having a bottom plate l2, 2. side wall l3 and cover sections l4; Partitions l6 divide this tube-like structure into four sections. It is obvious that the'tub might be divided into a difierent number of sections, if so desired. Byviewing Fig. 2,

it will be noted that the cover sections I 4 are so arranged as to cover each section separately. A

1 centrally disposed perforated tubular member I! I is centrally positioned in the tub and supports at its upper end a funnel l8. Mounted in the bottom of each section of the tub are plunger plates I9, which plates may be reciprocated. by rods 2| and 22. The rods 22 are connected to a pusher plate 23, and the rods 2| are connected to a pusher plate 24. These rods pass through the bottom l2 and may be provided with packing glands, which have not been shown. A power driven shaft 26 is connected through gears 21 in such a manner as to rotate eccentric wheels 28 positioned between the plates 23 and 24. The shaft 26 may be driven in any convenient man ner. Here I have shown a motor 29 driving the pulley 3! through the medium of a belt 32 passing over the motor pulley 33. The bottomof the tub is provided with a downwardly extending stub 34, which is connected to a supporting shaft 36 rotatably mounted in a bearing 31, which bearing is mounted in a bearing block 38 and is cushioned by a rubber buffer 39. A pulley 4|, mounted upon the shaft 36, is driven by a belt 42, which is in turn driven by apulley 43 rotated by the motor 44, the purpose of which is to rotate the tub I0 during the drying action so that water will bcexpelled through'the openings 46 near the top of the tub.

A pipe 41 communicates with thebottom 9 of the casingand has its opposite end connected to a pump 48 which delivers discharge therefrom to a pipe 49, which in turn spills into the funnel l8, which in turn discharges into the tubular member II. A perforated supply pipe 5| extends through the funnel l8 and into the centrally disposed perforated tubular member. II. This supply pipe is connected to hot and cold water pipes from the compartments-formedon each side of the partitions IS, the water flowing into the bot- 52 and 53 through'valves 54 and 56,respective- These tom 9; The water can be discharged from the bottom 5 through a gate valve 6 controlled by a pull rod 51, which may be held in elevated position'by'pivoted dogs 68.

The operation of my device is as follows:

The covers I I are removed by loosening the hand screws 59, and each compartment is filled with clothes to be washed. The covers are then replaced, and the valves 54 and 55 are regulated to permit water to flow through the supply pipe 5! and the perforations, thence through the centrally disposed tubular member I1 and thence into the tub. Steam may also be admitted by.

opening the valve 58 andallowing the steam to flow through the pipe 51. After the proper amount of liquid has been introduced into the tub, the motor 29 is turned on, with the result that movement is transmitted through the connecting gearing to the eccentric wheels 22. These eccentric wheels 28 push upwardly on the pusher plate 23 and rods 22 and cause the plunger plates on each of the compartments to rise, as indicated in dotted lines in Fig. I. This action sucks fluid through the clothes and into the space beneath the plunger. When the top of' the stroke has been reached, the eccentric wheels then start to Y started. Consequently, the pulley l8 and-the belt 42 transmit motion to the pulley II and to The water trapped beneath thethe shaft 26, which in turn transmits rotary motion to the tub ll. As this rotary motion is at exceedingly high speed, the water within the clothes will travel outwardly and up the sides of the tub and escape through 'the'perforations 46 into the casing 8. The valve 68, being open,

will permit the water to drain away, and after a period of whirling, the clothes will be found dry enough to pass through the ironing machine.

During the washing period some water will slop over through the perforations l6, and this water will drain into the pump 48 and will be returned to the tub through the pipe 49.

Thus it will be seen that I have produced a device which will effectively wash clothes in large quantities at a rapid rate and, at the sametime, will keep various groups of clothes separated into their proper classification.

It'is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material,

size, shape and arrangement of parts may be re'-- sorted to without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described my' invention, I claim: In a washing machine, a base, a casing supported above said base, a vertically disposed shaft mounted on said base and extending into said casing, a tub carried by said shaft and concentrically arranged ,in said casing, partitions formed in said tub to form tub sections, perforations formed in the upper portion of the sides of each of said sections, each of said sections having a removable cover secured thereto, perforated plunger plates positioned in each of said sections, said plates having the same area as the exposed area of the bottom of'the sections, and

means for reciprocating said plunger plates.
